Fig. 1. AUCs of blood biomarkers at ICU admission to predict postoperative MAKE or AKI. Missing values: plasma NGAL (MAKE: N=1/9, no MAKE: N=2/91; AKI: N=2/9, no AKI: N=0/91), hepcidin-25 (MAKE: N=0/9, no MAKE: N=1/91; AKI: N=0/9, no AKI: N=1/91), plasma NGAL:hepcidin-25 (MAKE: N=1/9, no MAKE: N=2/91; AKI: N=2/9, no AKI: N=1/91). *Indicates biomarker with inverse relationship to endpoints. Abbreviations: AKI, acute kidney injury; AUC, area under the ROC curve; BNP, B-type natriuretic peptide; CK, creatine kinase; CKMB, creatine kinase myocardial band; CRP, C-reactive protein; ICU, intensive care unit; IL, interleukin; MAKE, major adverse kidney events; NGAL, neutrophil gelatinase-associated lipocalin.
